LINOTYPE-MACHINE.

SPECIFICATION forming part of Letters Patent No. 606,168, dated J une 211898.

Application tiled April 18,1896. Serial No. 588,167. (No model.)

To all whom t may concern,.-

Beit known that I, THOMAS H. KELLER, of New York city, county of NewYork, and State of New York, have invented a new and useful Improvementin Linotype-Machines, of which the following is a specification.

My invention relates to improvements in linotype-machines-such, forexample,as that shown in Letters Patent of the United States No.436,531, dated September `16, 1890, in which a slug of type-bar isejected from a mold, in which it is formed between two trimming-knives,into a galley or receiver. These machines are frequently adjusted tochange the thickness of the slugs produced. Achange in the thickness ofthe slug produced necessitates a corresponding change in the distancebetween the trimming-knives. Heretofore this change has been effected byunbolting one of the knives, changing its position, and again boltin git fast, the adjustment involving also the substitution of one pair ofspacing blocks or liners for another to secure the required accuracy ofadjustment. Myinvention has in View the speedy adjustment of the knifeto different positions without the disconnection of any of the parts. Tothis end I mount the movable knife on inclined guides, so that whenmoved endwise it will also be carried forward or backward. I combinewith the knife thus mounted adjustable stop devices to limit itsmovement and a lever or equivalent operatingdevice by which it may beinstantly moved from one predetermined position toanother.

I have represented my improvement as applied to the ordinaryMergenthaler linotypemachine, which may be in all other respects ofordinary construction.

Figure 1 is aside face View of the viseframe,77 so called,with theknives in position thereon. Fig. 2 is a cross-section on the line 2 2 ofthe preceding figure. Fig. 3 is a rear face view of the adjustable knifein an alternative form.

Referring to the drawings, A represents 4 part of the frame commonlyknown as the vise-frame, and B a fixed trimming-knife, and O the movabletrimming-knife. The two knives stand in an upright position and theoutgoing slug is trimmed between their edges in the ordinary manner.

rlhe knife B is bolted rigidly to the frame inthe ordinary manner, butthe knife O is obliquely guided, so that when movable endwise itwillalso move toward or from the knife B.

In Fig. 1 the bolts D pass through'oblique slots in the knife into theframe beyond and, if desired, through 'oblique ribs formed on the knifeand seated in grooves in the frame. The bolts serve to hold the knifesnugly in place against the frame and to guide or assist in guiding itso that its front edge is at all times parallel with that of the knifeB. The bolts are commonly tightened in such manner 4that they will holdthe knife in the position to which it may be adjusted, while at the sametime they permit it to be removed by reasonable force.

F is a hand-lever pivoted to the frame and jointed at one end to theknife O, so that by means of the lever the instantaneous adjustment ofthe knife maybe effected.

G and H represent two independent adjustable stop-screws mounted in theframe opposite the two ends of the knife O in order to arrest itsmovement in opposite directions, and thus limit the distance between itand the stationaryknife. By adjusting these screws the knife adjustmentmay be controlled with great accuracy, so that the machine will trim theslug to the precise thickness required.

-When the end of the lever is depressed, the knife O will be raised anddrawn backward until arrested by the upper stop G, and in this positionthe machine is adapted to trim slugs of the maximum thickness required.

When the lever is raised, the knife is carried downward and inward untilarrested by the stop H, and in this position the machine will trim slugsof minimum thickness.

l The essence of the invention resides in mounting the knife on obliqueguides and in combining therewith stop devices to arrest the knife intwo predetermined positions and means for effecting the movement by.suitable connections. It is obvious that in place of the lever anyequivalent contrivance familiar to the mechanic may be employed and thatin place of the slots and bodiesother equivalent oblique guides may besubstituted. For example, the knife may be con- IOO structed, as shownin Fig. 4, with a single ob lique guiding and supporting rib on its backto enter a groove in the frame.

Having thus described my invention, what I claim isl. Inalinotype-machine the combination of the stationary knife, a movableopposing knife having its edge parallel therewith, oblquely-arrangedguiding devices for the movable knife, independent adjustable stops tolimit the motion in opposite directions, and

a mechanical means for effecting the movenient at will.

2. In a linotype-machine the combination of a stationary knife, anobliquely-guided knife,

a lever whereby the latter may be moved end` wise and stop devicesadjusted to permit the movement of the knife, but limiting its motion inboth directions whereby the knife may beinstantly adjusted to trim slugsof either of two predetermined thicknesses.

In testimony whereof I hereunto set` my "hand, this 14th day of April,1896, in the presence of two attesting witnesses.
